The invention discloses an on-line detection method and device for the tip leakage of a hollow-core filter tip cigarette. The on-line detection method is characterized in that the filter tip of the cigarette is detected online in the axial detection and the side detection by adopting detection optical cables, the filter tip leakage or a solid core filter tip of the cigarette is distinguished by using a processing circuit or a computer according to a detection electric signal, and unqualified cigarettes are rejected by an executing mechanism arranged on a production line, and thus the product quality is ensured. The on-line detection device comprises an axial amplifier, a side detection amplifier, a processing circuit or the computer, an axial detection optical cable, a side emitting optical cable and a side receiving optical cable, wherein the axial detection optical cable, the side emitting optical cable and the side receiving optical cable are arranged on a detection head. Compared with the prior art, the on-line detection method has the advantages of meeting the on-line detection requirement of two different cigarette tips, namely a conventional filter tip and a novel hollow-core filter tip, and being high in accuracy; the on-line detection device has the advantages of simple structure and strong universality, and is especially suitable for the on-line detection on production of various cigarettes.
Description
[0001] technical field [0002] The invention relates to the technical field of on-line detection, in particular to a method and device for on-line detection of a chipped hollow-core filter cigarette used in cigarette production. Background technique [0003] During the cigarette production process, it is necessary to carry out quality inspection on quality parameters such as the porosity at the end of the cigarette, air leakage and mouth gap, and reject unqualified cigarettes. Taking the Protos winding unit as an example, the cigarette on-line detection device uses a photoelectric switch to detect the gap, capacitance or infrared on-line cigarettes with loose ends. A diffuse reflection photoelectric switch is set on the side of the filter. A capacitive or infrared detection head is set on the opposite side of the switch, and the two detection devices are assembled by fixed components and installed on the production line of the cigarette machine. Quality inspection of end p...
